Abstract: A device for producing an electrode laminate includes a roller configured to press an active material layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer. A diamond-like carbon film having an average roughness of 0.16 ?m or less is on a surface of the roller in contact with an active material layer or a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 ?m or less is on a surface of the press sheet in contact with the active material layer.

Abstract: A method of producing an all-solid battery includes pressing a laminate in a state where the laminate is insulated from a press machine. The laminate includes a negative electrode current collector layer, a negative electrode active material layer, a solid electrolyte layer, and a positive electrode active material layer. The negative electrode current collector layer includes copper, at least one of the negative electrode active material layer and the solid electrolyte layer includes a sulfide solid electrolyte, and the press machine is an anisotropic press machine.

Abstract: According to the method for manufacturing electrode sheets, in a first cutting step, an original sheet, including a belt-shaped metal foil and an electrode material coated thereon in a lengthwise direction to form a plurality of coated portions spaced at a predetermined gap, is cut at a location between the coated portions. In a pressing step, the original sheet strips having been cut in the first cutting step are pressed. In this case, the original sheet strips that are pressed by the rolling device are independent from each other. Therefore, the effect produced in rolling of the coated portions remains within each of the original sheet strips. In addition, distortions occurring in the original sheet strips can be prevented from affecting each other and the occurrence of wrinkles can be inhibited.
